Our tattoo stickers are primarily made from extracts of the gardenia fruit, a plant in the madder family. 我们的纹身贴主要由茜草科植物栀子提取物制成。

Upon contact with the skin, the extracts in our tattoo stickers undergo an organic reaction with the protein on the outer layer of the skin's corneocytes, resulting in a blue coloration that deepens over time to a blue-black hue. 当与皮肤接触时，我们纹身贴中的提取物会与皮肤角质层上的蛋白质发生有机反应，导致皮肤呈现蓝色，随着时间的推移，这种颜色会逐渐加深为蓝黑色。

The color of our tattoo stickers typically lasts for 2-4 weeks, as they reside only in the layers of the stratum corneum. As the corneocytes undergo natural exfoliation, the tattoo gradually fades away without leaving any residue or side effects on the skin. 我们的纹身贴颜色通常持续2-4周，因为它们仅存在于角质层。随着角质细胞的自然代谢，纹身将逐渐褪色，并在皮肤上不留下任何残留物或副作用。
